<A HREF="http://www.cio.com/blog_view.html?CID=25657">A hacker broke into Google's main official blog</A> and posted a false message on Saturday, saying that the company had decided to cancel a joint project with eBay. The intrusion marks the second time this year that Google's official blog has fallen into unauthorized hands. In March, Google staffers deleted the so-called Google Blog by mistake and someone briefly took control of the Web address.
